A lot folks have had trouble with the on-off switch of their DW 788 scroll saw. What happens is saw dust can get into the switch and impact onto the contacts of the switch causing it to fail. Some people like to use compressed air to clean their saws.
The problem is this can force saw dust into the switch and cause it to fail. Naturally I would advise against using Compressed air for this purpose.
I keep a small brush next to my saw to brush off the dust from around the switch to keep it clean.
If your careful, you can disassemble the switch and clean the contacts with 220 grit sandpaper. Unplug the saw before performing any maintenance.

That is a great tip! The switch is the only real thing I hear of that people with the DW have trouble with. Thanks for your post.

I tried compressed air, and it didn't work, infact I had problems starting it, but finally got it to work. What I did I took some sticky press seal and adhered it over the switch, works great. Edward

I heard a lot about the switch problems when I first got my DW788 . I read of people adding a foot switch and then covering the switch on the saw with packaging tape. Seems to work great. The foot switch is the best thing I've done as well as replacing the Dewalt light assembly with a flourescent light with a magnifier. I can use just the light, just the magnifier or both at the same time.
Happy Scrolling

Edward, Using compressed air will make it worse! My point was to not use it.
ufgator, Yes a lot of scrollers like to use a foot switch, but for me I don't, so I try to keep the switch as dust free as possible.

My DW788 switch started acting up. That's when I got the foot pedal. I'm glad I did because it's awesome! Love it!

I haven't had a problem... yet, but you never know! I just give it a quick pass over with my shop-vac once in a while.

Ok Dan--here's one for you. I use a foot switch with my Dewalt. yesterday I was cutting and the saw just stopped. thought it might be a fuse. So I popped out the fuse holder , dropped it, and then stepped on it as I was turning to see where it went to. new fuse holder $25. Can a guy just put an inline fuse on the two connections. also can a switch go bad even if you are using a foot switch. I didn't have mine covered--Richard aka thumbs

Thumbs, I don't know about the fuse but yes the switch can go bad even if you don't use it. If it is not covered saw dust can still get into it and get between the contacts. If your careful you can take the switch apart and clean the contacts. If you don't use the switch you can even wire the switch out, if you know what your are doing!
